IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters PatentNo. 137,81 2, dated April15, 1873 application file September 16, 1872.

CASE A.

To all whom it may concern:

Be it known that I, GEORGE W. N. YsT, of Corry, Pennsylvania, haveinvented an Improved Bush-Holder for Mowing and Reaping Machines, ofwhich the following is a specifioation:

The nature of the invention is in the arrangement of a detachable bushholding sleeve within the main frame of a mowing and reaping machine soas to hold it therein by the gearwheels and hold it from revolving by aspur.

The accompanying drawing, with the following description thereof, fullyillustrates the invention.

Figure l represents a view of the parts combined. Fig. 2 represents aview of the inner sides of the casing-plates ofthe inclosing-box mainframe. Fig. 3 represents a lengthwise view of the bush-holder with thejournal-bearing bushes therein. Fig. 4 represents an end view ofthebush-holder with the journal-bearing bushes therein. Fig. 5 represents aplan view of the bush-holder.

' The following is the description: A represents a main axle, or twomain axles combined, of a mowing or reaping machine. B represents aleft-side driving-wheel on the main axle A. B represents a right-sidedriving-wheel on the main axle A. C represents a left-side metalcasing-plate on the main axle A, between the driving-wheels B B. Crepresents a ri ght-sidemetal casing-plate on the main axle A, betweenthe driving-wheels B B. a represents alug or ear,half cylindrical, apart of, and projecting out from, each end of the left-side casing-plateC. a represents a like lug or ear at each end of the right-sidecasing-plate C. The combination of the projections a a of thecasing-plates C C', when the casing-plates are combined into aninclosing-box or main frame, makes lugs, whereby the plates are fastenedfirmly together by bands around the hubs, and whereby theconnecting-frame may be attached to the main frame. b represents a rib,a part of, and projecting up from, the bottom and in from the side ofthe fore part of the'left oasin g-plate C. L represents a like rib ofthe right casingplate C. c represents a circular groove in the ear a andrest b of the left casing-plate C, in the plane of, and in line at aright angle to, the main axle A. c represents a like groove in the ear aand rest b of the right casing-plate (l. Uniting the circular grooves oc of the ears a o and rests b b of the casing-plates C C', when thecasing-plates are combined into an inclosing-box or main frame, makes ahole for a journal-bearing bushholder. d represents a recess in the foreear a of thevleft casing-plate C, projecting radially out from thegroove c. d represents a like recess in the right casing-plate C.Uniting the recesses d d of the fore-ears a a' ofthe f casing-plates CC', when the casing-plates are combined into an inclosing-box ormain-frame, makes a slot at a right angle to, and out from, thebush-holder hole c c. D represents a metal tube or sleeve or bush-holderlying within, and extended through, the hole c c of the inclosing-box ormain frame O C. e represents a spur projecting radially out from thefore end of the bush-holder D, and adaptedto, and put within, the recessd d of the inclosing-box or main frame C C. E represents a metal bushfor a journal-bearing within each end of the bush-holder D.

In this way I hold the journal-bearings of the crank-wheel axle, forwhich the invention is peculiarly well adapted, though it also is goodfor the journaLbearings.

The small bevel-pinion on the inner end, and the crank-wheel on theouter end, of the crank-wheel axle prevents the sleeve D, while in use,from moving endwise; and the spur e within the recess d d of the mainframe G C prevents it from revolving. It is a fraction smaller than thehole o c of the main frame, so that it can be taken out and putin by theingers.

Thus, when a bush, E, gets worn out the bush-holder D can be removedeasily to replace or repair the bush, and can be held firmly and solidlywhen in place within the main frameC C.

The essential feature y of the invention is the combination of the`loose tube or sleeve UNITED STATES PATENT GFFICE.

with a tubular part of the main frame of a mowing or reaping machine,When heid therein in the manner described7 and prevented from revolvingby a spur of the sleeve in a recess in the frame.

The following is a summary of what I claim and desire to have patented:

The arrangement of a detachable bush-holding journal-bearing sleevewithin the mainl frame 0f a mowing or reaping machine, when held thereinby gear-Wheels on the axle Within such sleeve, and prevented fromrevolving by a spur, substantially as described.
